Is Hyrum hard water?
At 217 mg/L (13 gpg), Hyrum sits in the very hard band — above about 10.5 grains per gallon is very hard on the USGS scale. Scale shows up first inside the water heater, then on fixtures and glass. See the hardness scale.
Worth knowing: The city's Culinary Water page states an unexplained unitless 6.5-7.5 that conflicts; worth a call before leaning on this.
Scale builds inside the heater before it is visible anywhere else.
What Hyrum’s hardness means in practice
Sizing is arithmetic once you have a number. At 13.0 grains per gallon — the published figure — a household using the EPA average of more than 300 gallons a day sends roughly 3,900 grains of hardness through its plumbing every day. Over a year that is about 203 pounds of scale-forming calcium and magnesium passing through the water heater and the fixtures.
Against that load a 32,000-grain softener would regenerate roughly every 8.2 days and a 48,000-grain unit about every 12.3 days. Those are first estimates off the figure Hyrum publishes, not a quote: your own use, any iron in the water, and whether you want softened water at the kitchen tap all move the answer, which is why we measure at your tap before sizing anything.
What CASA recommends in Hyrum
A softener sized to Hyrum’s published hardness is the first thing worth doing here. Add reverse osmosis at the sink for drinking water and whole-home carbon for chlorine.
